Here's how the lyrics go ... "Might run across your mind but don’t worry ’bout me, no//My heart is back in one piece, it ain’t skipped a beat, no Feeling rested up, I ain’t missing sleep, no-oh//Don’t take it personal if I can’t reply now. I’m distant ’cause I don’t wanna be reached now//Won’t let the ghosts of our past weigh my future down." That is TOTALLY about Selena! Listen to it ...
